After Coming Down the Mountain, I Was Already Half a Grim Reaper

This is another world, a classic world of swords and magic. But for reasons unknown, it has been influenced by other worlds, in culture, technology, and abilities. As a result, some places are still primitive tribal lands, while others have reached the age of modern technology. Some people have even gained abilities from other worlds, such as the Knight King's Curry Stick, the Heroic King's EA, Ulquiorra's Thunder Spear, and the Slayers' Explosion Magic. The emergence of these abilities has changed the whole world. Of course, this world is not as simple as it seems... Our protagonist, Su Yuzhe, has never once descended the mountain, but his master has now sent him down. He is half a Shinigami, and will adventure through this world, uncovering the mystery of his origins, gathering the rest of his Shinigami powers, and making friends along the way... But is that really all there is to it? As he ventures on, the secrets and true nature of this world will gradually come to light, and he will be swept into the open and covert struggles between the gods.
